INDIANAPOLIS - A judge has set bond at $100,000 for an Indiana man charged with threatening a school massacre and telling his wife he would stab her with a screwdriver and kill her children and grandchildren.

Sixty-year-old Von Meyer of Cedar Lake has been charged with intimidation, domestic battery and resisting law enforcement.

Police boosted security at Jane Ball Elementary School in Cedar Lake and three other area schools Friday after Meyer's wife told officers he had threatened during an argument to "shoot up the school." She works at the school's cafeteria.

The alleged threat occurred hours before 20 students and six adults were shot and killed at an elementary school in Newtown, Conn.

Police found 47 guns and ammunition hidden throughout Meyer's home after they arrested him Saturday, but a police official says most of the weapons were antique collector guns and that he believes Meyer was not serious about his school threat.
